GOUVERNEUR GEALES RHOER, OF LITTLE ROCK, ARKANSAS.

UMBRELLALOCK.

Application filed July 31, 1917.

To all 'whom t may concern:

Be it known that I, GoUvnnNnUu C'nALns RHonn, a citizen of the United States, residing at Little Rock, in the county of Pulaski, State of Arkansas, `have invented certain new and useful Improvements in Umbrella-Locks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will .enable others skilled in the art to which it appertains to make and use the same.

This invention relates to staff sockets for umbrellas, and has particular reference to sockets in which a staff may be located.

The object of the invention is to provide an improved form of device for receiving and locking into place the steill of an urnbrella of that type which is used upon carriages and wagons and is generally mounted upon the drivers seat. More particularly my invention consists in the provision of a socket within which a staff may be locked, a suitable key controlled locking device being mounted at the side of the socket which is key controlled to prevent or permit the removal of the staff.

With the above objects in view and such others relating to the details of construction as may hereinafter appear, my invention will now be fully Set forth and described, reference being had to the aecompanying drawings In the drawing Figure 1 is a side elevation of the device in use,

Fig. 2 is a vertical section through the entire device,

Fig. 3 is a section on line 3 3 of Fig. 2, and

Fig. 4 is a section on line 1 -4.- of Fig. 2.

Referring more particularly to the drawings, 1 represents a tubular socket of suitable depth to properly support and brace the end of a staff 2 which, in the present instance is the end of an umbrella standard, though it may obviously be any similar or analogous device. The standard is mounted either upon a baseor on the back of a earriage or other vehicle seat in an obvious manner. At its lower end, the socket is internally provided with a coil spring 3 whose lower end is secured in position, and whose convolutions provide a cushion for the lower end of the staff 2. Vertically secured to, or formed on the interior surface of the socket is a rib 4 which preferably Specification of Letters Patent.

extends through the length of the socket, and cooperates with a corresponding groove cut into the stall' 2, so that the latter is prevented from rotation within the socket. Upon the statt' 5, at a point within the limits of the portion which lits within the socket 1, is a lug or knob 5 which is preferably located diametrically opposite the groove ll, said lug being adapted to appear opposite a vertical slot of short duration which is formed in the wall of the socket 1, the lug appearing opposite the socket when the staff is pressed downwardly to compress the spring in the bottom of the socket. The slot 6 provides an entrance for a latch 7 which is formed upon the lower end of an arm 8. The arm 8 is a continuation of a coil spring 9 which 4is mounted to rock upon a spindle 10 having its bearings in the walls of a lock casing 11 which is suitably bolted 0r clamped to the inside of the socket 1. The spring 9 tends to throw the latch into the opening or slot 6 so that it may normally be positioned to snap into engagement above the lug 5 when the staff is pushed downwardly in the socket. A leaf spring 16 secured to the side of the casing also tends to throw the arm 8 into position. Above the spindle 10, the spring 9 is continued in a spring arm 12 which is positioned to be engaged by the head of a key 13 when the latter is projected through the key slot 14. The head of the key 13 is shaped with a cam face 15 which is adapted, when the key is projected through its key slot to tension J[he spring arm 12, so as to withdraw the latch 7 from the slot 6, when the key is drawn into vertical position, it again releases the spring arm. Obviously, when the key is removed, the spring arm stands free to permit the latch to project into locking position.

In the use of my device, the standard 3 may be dropped into the socket, and. sup- 100 ported upon the head of the spring cushion in freely removable relation. However, when pressure is exerted on the staff to shove it down within the socket, the spring 19 is compressed, and the latch 7 is snapped 105 above the lug 5. In order to release the latch 7 from the lug, so that the staff may be removed, the key is employed in the manner above described. It should be remembered that the lug 5 may be substituted 110 by a notch in the stall into which the latch 7 is projected.

It will be apparent from the foregoing that l have provided a simple and practical device for securely holding a stall in position against accidental or unauthorized removal, and that the device may be readily applied to vehicle seats or bodies without great expense or labor.

What I claim as my invention is A staii socket,V comprising in combination, a tubular element, a spring cushion in the body of said element, a vertical rib formed longitudinally throughout the length of the socket, a staff adapted to seat Within the socket element and having a vertical groove to coperate with said rib to prevent rotation of the sta-if, a lock casing mounted upon the socket element, a transverse pin eX- tending across the casing, a spring latch mounted on said pin and having an end @erlie of chie patent may be obtained for wardly extending element carrying said projecting end, and a spring to force the downwardly extending element toward the wall of the socket element, a key for controlling the spring latch, and a lug provided on the staff for engagement by said latch when the sta is depressed in the socket element against the action of said spring.

In testimony whereof, l' affix my `signature in the presence of two witnesses.
